Application filed September 20, 1901. Serial No. 75,741. (No model.)

run, in the county of Muskingum, State of.

Ohio, have invented certain new and useful Improvements in Wire-Grips;andIdo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to wire-grips; and it has for its object toprovide a device of this nature, such as used in connection withwirestretchers, which will be simple and cheap of construction and whichwill'be most durable and efficient.

A further object of the invention is to provide a grip in which the jawswill have a most positive gripping action and in which the parts may beeasily and quickly disconnected for substitution of new parts or forrepair, other objects and advantages of the invention being understoodfrom the following description.

In the draw ngs forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a perspective view show ing the wire-grip, the parts beingshown in position to engage a wire. Fig. 2 is a bottom plan view of thedevice. Fig. 3 is a perspective view of the main frame of the grip. Fig.4 is a bottom perspective View of the follower. Fig. 5 is a top planView of the follower with the central plate removed. Fig. 6 is a detailperspective view of the strengthening-plate.

Referring now to the drawings, there is shown a grip comprising a mainframe including a stem or body portion 10, at one end of whichis formeda broadened head 11, which is slotted longitudinally from one end toform the spaced fingers 12 and 13 and the intervening interspace 14, thefingers having their end portions bent first upwardly at 15 and 16 andthen rearwardly at 17 and 18 to lie parallel with the upper face of thehead to form two guideways, as shown, and in these guideways is disposedthe follower 19. The follower consists of a plate of metal the sides ofwhich are bent first upwardly and then toward each other to lie aboveand parallel with the face of the plate, and in corresponding ends ofthe upwardly-bent portions thereof are formed openings in which arereceived the arcuate gripping-jaws 20 and 21, having theirgripping-faces serrated and which are mounted upon pivots engaged withthe plate, so that as they are rotated in one direction the serratedportions will be brought together to exert a gripping action upon a wiredisposed therebetween and when rotated in an opposite direction willliberate the wire.

In practice, as shown, the bent-over portions of the plate of thefollower are disposed beneath the bent-over portions of the fingers ofthe main frame, so as to slide in the guideways formed thereby, and tohold the follower against lateral displacement a longitudinal rib 22 isformed upon the under side thereof and is engaged between the fingers.

It will be noted that the outer ends of the arcuate gripping-jaws arehooked, and these hooked portions are engaged over stops in the form ofhooks23 and 24 at the ends of an 'arcuate or yoke-shaped plate 25, whichis riveted or otherwise attached to the stem of the main frame, the endsthereof having the hooks extending parallel to the line of the tips ofthe fingers l2 and 13. The stops are so located and the dimensions ofthe parts are such that when the follower is moved to its limit in thedirection of the stern of the frame and the jaws are engaged with thestops the gripping portions of the jaws will be separated to permit ofpassage of a wire therebetween, and if the follower be then moved in theopposite direction, the pivots of the jaws being carried rearwardly, thejaws will be moved by thestops pivotally to bring the gripping portionsthereof together.

To insure engagement of the jaws with the wire, the follower is heldnormally and yieldably in its last-named or rearward position by meansof a helical spring 26, which is disposed upon a rod 27, having a head28, provided with a tooth 29, removably engaged in the recess inthe rib22 of the follower, the other end of the rod being slidably engaged witha perforation in a lug 31 upon the under side of the stem of the mainframe. The spring by resting with one end against the lug 31 and theother end against the head of the rod holds the follower yieldablyretract ed, as stated.

- the outer faces thereof.

The outer end of the stem of the main frame is adapted for attachment toa support for holding it in operative position or may be connected withsuitable means for moving it for use as a wire-stretcher.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from the spirit of the invention.

What is claimed isl. A wire-grip comprising a frame having guideways, afollower mounted in the guideways and having pivoted jaws, fixed stopsin the paths of movement of the jaws, for engagement thereby beyondtheir pivots, and means for moving the follower with the-jaws intoengagement with and against the stops to move the jaws into engagingpositions.

2. A grip comprising a frame having guideways,a follower mounted in theguideways and having pivoted jaws, fixed stops disposed in the paths ofmovement of the jaws for engagement by the jaws beyond their pivots tomove the jaws into engaging positions, and means for moving and holdingthe follower yieldably at one limit of its movement, to move and holdthe jaws yieldably in engaging positions.

3. A grip comprising a frame including a plate having one end bifurcatedto form fingers, said fingers being bent to lie above the plate and formspaced guideways, a follower engaged slidably with the bent-overportions of the fingers and having a rib disposed between the fingers,jaws pivoted in the follower, a helical spring disposed between the ribof the follower and the frame to hold the follower yieldably at onelimit of its movement, and stops in the path of movement'of the jawswith the frame to move the jaws pivotally.

4. A grip'comprising a frame including a plate having one end bifurcatedto form fingers, said fingers being bent to lie above the plate and formspaced guideways, a follower engaged slidably with the bent-overportions of the fingers and having a rib disposed between the fingers,said rib having an opening therein, a perforated lug upon the frame, arod having a lug at one end engaged with the opening of the rib, theopposite end of the rod being slidabiy engaged with the perforation ofthe lug, a spring upon the rod having its ends disposed against the lugsof the frame and rod to hold the follower yieldably at one limit of itsmovement, jaws pivoted in the follower, and stops in the paths ofmovement of the jaws with the follower under the in fluence of thespring, to move the jaws into engaging positions.

5. A grip comprising aframe having a movable follower mounted thereonand provided with movable jaws, and fixed stops carried by the frame inthe paths of movement of the jaws of the follower for engagement therebyto move the jaws into engaging positions.

In testimony whereof I affix my signature in presence of two witnesses.
